ToaZZ wh-omitmay concern Be itiknown tliatl, Emma-n L, G. CLARK, a citizen of the United Statesgresidingmt. Tiaunton, in, the. county Oil Bristol and State OfwNlZISSQCh USElJtS, have invented certaln new.

for Printingfiressesa of which :tliefollowing is-.aspecification.

The invention has for, its. prineip al ,1 ob,- jec-ts-the. provision of an ink :fountaan {mesh 1 a-nism providingfor swingingthe ink: blade. between iL POFSltlQII'IlIl' operative; relation to the roll: and at position removed: from y the roll and; readily accessible..- for: cleamng; and the like, and combined therewithmeaa sifor V-ari ably adj usting gthe inkgblade throughout its; length, and so arranged las. inottto ,be d1 s turbede in the A swinging of, the blade out; ofr andE againinto: operativepositlOnj relativeto the. inle roll; also other; novel and'advantageous characteristic, features which wlll. hereinafter be made apparent.

In orden that; the;- constructional features. of: the invention and atheir mode -1 of, opera am may be readily. understood; by those skilled in this art a preferred.emlaodlment v of. thesame is set; forth gin ,thes accompanyin.gdrawings .and in the subjojaiedy descrip tion, based. thereon.

In orderthattheamount of ink trans ferred; to the-ink; roll 11- maybe varied locally throughout itslengthE as thenature of the work requires, it is necessary that the; relation between the periphery of thepink roll andztheedgeof the-inle plate'shall be absolutely, controllable throughout the length of, the plate, and Eto provide. fortthis independent. adjustment set. screws 23 are-- ineunted at. frequent intervals longitudhnally ofthemember. 1%? being, arranged: obliquely with, reference to the; pl-atewith, their. coned. forward ends 2 B bearing uponthe margin-10f. the: ink, plate: 22 from theunder side thereof closely. arljacent tlie edge. These set. screws being independently. adjustable witl1in.the-- trough. bottom 1 L it is madepossible to closely regulateithe :161211- tion between the roll and v plate throughout. the: length thereof.

Uppnqthe. shaft,12. of the inlnrol-lnis fixed a ratchet wheel 25 engaged by the pawl 26 carried by a pinion 27 which is loosely mounted for oscillatory movement upon the said shaft 12, The pinion 27 is in mesh with a rack 28 arranged to be reciprocated through the link 29 from any convenient moving part of the press. It will be observed that as the reciprocatory rack 28 moves backward and forward the pinion 27 is oscillated and by means of the pawl 26 advances the ratchet 25 step by step thus also rotating the ink roll step by step to transfer the ink from the fountain to the ink distributing train.

In order to provide for the manual rotation of the ink roller during the preliminary inking up, a hand crank 30 is provided which has a nave formed as a housing 31 surrounding a star cam wheel 32 fixed upon the shaft 12, and within the housing in operative relation to the inner wall thereof and to the cam faces of the star wheel are disposed a plurality of rolling members such as rolls 33. It will be clear that when the crank is rotated in a clockwise direction the housing 31 will be clutched to the cam wheel 32 and thereby the ink roll carried by the shaft 12 will be rotated, and that when the ink roll is rotated by means of the step by step driving mechanism previously described the clutch connection between the housing and cam wheel will be released and the crank 30- will remain inactive, hanging idle.

I claim:
